The electronic equipment establishes a three-dimensional model of the offshore platform through BIM technology or other 3D model establishing technology, and position information of each staff is directly displayed on the three-dimensional model.
Step S102, judging whether at least one worker is abnormal or not based on the position information.
For the embodiment of the application, the electronic device judges whether at least one worker is abnormal based on the position information, the position information can intuitively embody the travel route of the worker, and if the travel route is abnormal, the worker is indicated to be likely to be abnormal. The abnormality of the position information can be divided into three cases, one is disappearance of the position information; secondly, position information is mutated; thirdly, the location information remains stationary for a long time.
Step S103, if an abnormality occurs, monitoring data is obtained, and the cause of the abnormality is determined based on the monitoring data.
For the embodiment of the application, if the electronic device determines that the position information is abnormal, the electronic device acquires the monitoring data, determines the abnormal reasons based on the monitoring data, wherein the abnormal reasons include that the device is in fault or harmful gas leakage is caused in the construction process, and the like, and the monitoring data can accurately determine whether the environment or the device is abnormal or not, so that the direct reason of the position information abnormality is obtained.
And step S104, early warning information is sent to other staff based on the abnormal reasons.
For the embodiment of the application, the electronic equipment sends the early warning information to other staff based on the abnormal reasons, so that the staff is warned, the staff can be prevented in advance, and the possibility of accidents is reduced.
In one possible implementation manner of the embodiment of the present application, step S102 includes steps S1021 (not shown) and S1022 (not shown) of determining whether an abnormality occurs in at least one worker based on the location information, where step S1021 determines whether the number of location information reaches a preset number, and determines whether mutation location information and/or rest location information exists.
The rest position information is position information that the rest time reaches a preset time.
For the embodiment of the application, the electronic equipment judges whether the number of the position information reaches the preset number, the preset number is the number of staff on the offshore platform, the preset number of the electronic equipment can be obtained from equipment for attendance or card punching of the staff, the staff can check in through face recognition or card punching, the electronic equipment or check-in data are obtained, and then the preset number is obtained. For example:
assuming that the number of the position information is 98 and the preset number acquired by the electronic device is 100, the electronic device judges that the number of the position information is smaller than the preset number.
The electronic equipment judges whether mutation position information and/or rest position information exists or not, the electronic equipment judges whether the medal is in the mutation position information and/or the rest position information based on the position information at different moments, the rest position information is the position information which is kept for a preset time in the current position information, the preset time can be set according to working conditions, abnormality can occur when the position information of the offshore platform is not changed for a long time, and the preset information can be set to be 10 minutes.
Step S1022, if the preset number is not reached, and/or mutation position information and/or rest position information exist, determining that at least one worker is abnormal.
For the embodiment of the application, if the electronic device determines that the number of the position information does not reach the preset number, it is indicated that the position information disappears, that is, the staff may disappear, so that the electronic device determines that at least one staff is abnormal. If the electronic equipment determines that the number of the position information reaches the preset number, the staff are all indicated to be in the monitoring range. Take step S1021 as an example:
the electronic equipment judges that the number of the position information is smaller than the preset number, and then the electronic equipment determines that 2 pieces of position information are absent, so that the situation that 2 workers are abnormal is indicated.
If the electronic equipment determines that the mutation position information exists, the situation that the worker is dropped is indicated, if the rest position information exists, the situation that the worker is syncope and choked is indicated, and the worker is kept in place, so that the abnormality of at least one worker is determined.
One possible implementation manner of the embodiment of the present application, the method includes step S105 (not shown in the figure), step S106 (not shown in the figure), and step S107 (not shown in the figure), where step S105 may be performed after step S1021, where,
Step S105, if the number does not reach the preset number, the positioning accuracy is reduced, and further the position information with larger area is obtained.
For the embodiment of the application, if the electronic device determines that the number of the position information does not reach the preset number, the electronic device reduces the positioning accuracy, and the electronic device can adjust the positioning accuracy to 2-5 meters by adjusting the setting of the RISSI value so as to reduce the positioning accuracy, so that the position information with a larger area is obtained, and the position information of the staff is prevented from being missed due to the overhigh positioning accuracy.
Step S106, judging whether the number of the position information reaches the preset number.
For the embodiment of the application, the electronic device determines whether the number of location information reaches a preset number, for example:
assuming that the number of the position information is 100 and the preset number acquired by the electronic device is 100, the electronic device judges that the number of the position information reaches the preset number.
Step S107, if the number does not reach the preset number, the steps of reducing the positioning precision, further obtaining the position information with larger area, and judging whether the number of the position information reaches the preset number or not are circularly executed until the positioning precision reaches the preset precision.
For the embodiment of the present application, assume that the number of location information acquired by the current electronic device is 50, taking step S1021 as an example:
The electronic equipment determines that the number 50 of the position information does not reach the preset number 100, and reduces the positioning accuracy to 2-2.5 meters; the electronic equipment obtains the number of the position information with new positioning precision to be 88, and if the electronic equipment determines that the number of the position information 88 does not reach the preset number of 100, the electronic equipment reduces the positioning precision to 2.5-4 meters; the number of the position information with the new positioning precision acquired by the electronic equipment is 98, if the number 98 of the position information determined by the electronic equipment does not reach the preset number 100, the electronic equipment reduces the positioning precision to 4-5 meters, the number of the position information with the new positioning precision acquired by the electronic equipment is 100, and the number of the position information determined by the electronic equipment reaches the preset number 100.
If the positioning accuracy reaches the preset accuracy, the preset accuracy is 5.5 meters, the electronic equipment stops reducing the positioning accuracy, and the possibility of reappearance of new position information is small because the area of the offshore platform is exceeded by reducing again. For example:
the number of the position information with new positioning precision obtained by the electronic equipment is 98, if the number 98 of the position information determined by the electronic equipment does not reach the preset number 100, the positioning precision is reduced to 5.5 meters by the electronic equipment, if the number of the position information determined by the electronic equipment does not reach the preset number, if the 2 position information is determined to be absent by the electronic equipment, the situation that 2 workers are abnormal is indicated.
The number of the position information is judged step by reducing the positioning accuracy, so that the number of the position information is more accurate.
In one possible implementation manner of the embodiment of the present application, the step S1021 determines whether mutation location information exists, which specifically includes a step S1021a (not shown in the figure), a step S1021b (not shown in the figure), a step S1021c (not shown in the figure), and a step S1021d (not shown in the figure), where,

The electronic device obtains historical position information corresponding to the historical time, for example: assuming that the preset number is 4;
the electronic device obtains 9:00:00 historical location information as (100,200,50);
the electronic device obtains 9:00:01 historical location information as (102,200,45);
the electronic device obtains 9:00:02 historical location information as (105,200,20);
The electronic device obtains 9:00:03 historical location information as (110,200,5).
Step S1021b, fitting a motion curve based on the historical time and the historical position information.
For the embodiment of the application, the electronic equipment fits the motion curve based on the historical moment and the historical position information, and the electronic equipment determines that the staff mainly moves in the X axis and the Z axis based on the three-dimensional position information, and the movement amplitude in the Y axis direction is not large, so that the electronic equipment establishes a two-dimensional rectangular coordinate system through the coordinates of the X axis and the Z axis, and fits the motion curve based on the two-dimensional rectangular coordinate system. If the position information acquired by the electronic equipment is longitude and latitude, the electronic equipment directly establishes a rectangular coordinate system according to the longitude and latitude abscissa. For example:
the electronic equipment fits a motion curve based on (100, 50), (102, 45), (105,20) and (110,5), the electronic equipment can fit by a least square method, and the obtained motion curve is: y=0.2 x 2 47x+2758, where x has a minimum value of 100 and y has a minimum value of 0.

For the embodiment of the application, the electronic device judges that the slopes of the cloud top curves all have abrupt changes, and the electronic device can calculate a plurality of slopes at optional points in the motion curves so as to judge whether the slopes have abrupt changes. For example:
